How to export a motion tracked camera to 3ds Max?
I've been doing this a lot recently at my work. I find the following solution works best:


Create a cube and align it to the camera exactly, one face should point exactly where the camera faces and you should note which face this is
Parent the camera to the cube, so that the cube follows the motion of the camera, then bake the animation of the cube and clear the parent, you should be left with a cube that follows the track of your camera 
Note the framerate of your blender file, by default it is 24fps
Export the cube as a DAE file 
Open max and ensure your project framerate is the same as in blender, if it isn't the animation will look weird.
Import the DAE file into max and align a max camera to the cube in the same way the cube was aligned to the camera in blender.
Link the camera to the cube then bake the animation of the camera and clear the parent.

Check that your max camera has the same FoV / Focal length as your original blender camera.
